BEARING-SLEEVE FOR EXPANSION PIPE-JINTS.

SPECIFICATION forming' part 0f Letters Patent No. 730,425, dated June 9, 1903.

Application filed April l0, 1903. Serial lilo.v 15 1,957. (No model.) y

To all whom, it may concern,.- v

Be it known that I, HENRY J. WEssINGER, a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain neur and useful Improvements in Bearing-Sleeves for Expansion Pipe-Joints; and I do hereby declaro the following to bev a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to bearing-sleeves for expansion or slip joints for pipe-lines,` and particularly to such bearing-sleeves as are adapted for use at points where no independ-Q Q ing-sleeve of a plural number of parts, as 9 eut anchorage for the sleeve is obtainable.

It consists, in combination With a pipe member and a packing-sleeve member adaptedrto extend in part over a part of said pipe member, of a bearing-sleeve member mounted upon and closely grasping said pipe member and secured thereto and adapted to span orV arch over the pipe-inclosing end of said'packing-sleeve and to slidably grasp said packing-sleeve intermediate of the ends thereof.

It also consists of certain other constructions, combinations, and arrangements of parts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure l is a vertical central section through a construction embodying my said invention. Fig. 2 is a plan view of se' construction.

As shown in avvings, a pipe member 1 of uniform d` er is secured at one-endv to the end of aY ntiguons section 2 ofl the" main pipe-line and is adapted at its opposite end to extend into a telescoping packingsleeve 3, which is attached at its opposite end` to the end of a contiguous section 4.- of the main pipe-line. Said sleeve 3 is fora portion of its'length of considerably vgreater diameter than said pipe member l and is provided near its pipe-inclosing end with an in` ternal annular rib 5, against which suitable packing 6 may be shouldered by a gland member 7, positioned at the pipeinclosing end of said sleeve and extending into said sleeve and adjI ustably secured thereto by bolts S or other suitable means.

I am aware that certain portions of said joint have heretofore been described, and parbearing-sleeve.

box such as is described in said Letters Patent, and it is therefore desirable to construct a bearing-sleeve which is adapted to receive its sole direct support from the piping or joint itself and in turn to lend its support thereto. To accomplish this result, I construct a bearand 10,respectively, adapted when fitted together to form a longitudinally-divided sleeve cylindrical at each of its ends and of greater diameter at one end than at the other. `The central portion of said sleeve is considerably tudinally-arranged ribs 11 andl2, respectively, connecting the opposite ends of said The sides of said sleeve between said ribs are preferably left open, as at 13, through which openings the adjustable fastenings of said gland may be reached Without taking the sleeve apart Annular dovetail grooves 14: are preferably formed in the interior face of the larger end of said bearingsleeve to hold Babbitt metal 15, interposed between said portion and the packing-sleeve, upon which packing-sleeve that end of said ,bearing-sleeve is slidably mounted. The opf' posite end of said bearing-sleeve is preferably provided With an apertured attachingflange 16 to hold bolts by which it is secured to the flanges of said pipe members 1 and 2,

Which pipe member 1 said bearing-sleeve is adapted at its smaller end to closely grasp. A suitable number of apertured lugs, as at 17, are formed upon-each of the separate portions of said bearing-sleeve to hold bolts, as at 18, for securing said parts together.

Having now described my invention, what I claim, and desire to secure by Letters Patent, isv

l. In an expansion-joint for piping, the

IOG

of the end portions, the internal diameter of one 0f said end portions being greater than the internal diameter of the opposite end p0rtio'n, substantially as described.

In testimony whereof I have hereunto signed my name in presence of two Witnesses.

HENRY J. WESSINGER.
